Nel saying "Geez, I was so looking forward to meeting up with Ichigo too..." makes it seem like she might perish doing this... I can't see it being a time consuming thing unless it's just terrible writing :/? I can't imagine anyone will die though -_-;;;
Other then that, bottom of page 14, Urahra's Bankai being stretched to the limit before it collapses over him, stitching running all around his arms, on fingers, and extra on his face too. It's a pretty cool Bankai, wonder if he feels any pain while all that stitching is happening... wonder if the switches remain after or if he will be covered in scars.
